Yi Technologies teased the release of their tri-copter drone. The drone features the Yi 4K mounted on a 3-axis gimbal along with 40 minute flight time, speeds up to 75mph, and an entirely carbon frame. Yi is designing the Erida to be a straightforward and easy to use drone at a competitive price. We can expect a lot more details at Las Vegas’s InterDrone Convention of September 7th. We’ve reached out to Yi Technologies for more information.
